Abstract: A light-emitting device includes: a light guide that includes (i) a light-transmissive member that is light-transmissive at least in a visible light region and (ii) a light control layer that is disposed on at least a part of a surface of the light-transmissive member; and a light source that emits light toward at least one end surface of the light-transmissive member. The light control layer has reflected-wavelength selectivity that makes a wavelength of reflected light dependent on an incident angle of incident light.

Abstract: A light emitter includes a light emitting layer and a reflection layer. The reflection layer includes a first dielectric film and a dielectric multi-layer film. The dielectric multi-layer film includes at least one layer of laminated film, in which each layer of laminated film includes a pair of a second dielectric film and a third dielectric film. The first dielectric film has a refractive index lower than a refractive index of the light emitting layer and the second dielectric film. The third dielectric film has a refractive index lower than the refractive index of the second dielectric film. A relationship of d1≥λave/n1 is satisfied, where λave denotes an average wavelength of a spectrum of visible light emitted via the light emitting layer, n1 denotes the refractive index of the first dielectric film, and d1 denotes a film thickness of the first dielectric film.

Abstract: Three light-emitting units are included. Two light-emitting units of the three light-emitting units are similar-color light-emitting units that emit light in a similar color, and have mutually different luminance lives. A remaining light-emitting unit of the three light-emitting units is a different-color light-emitting unit that emits light in a color that is different from the similar color, and has a luminance life that is shorter than each luminance life of the two similar-color light-emitting units.

Abstract: A lighting apparatus includes a laser that emits laser light. A transmission component transmits the laser light. The laser light transmitted by the transmission component enters and is emitted by an optical connector. A wavelength converter emits wavelength-converted light according to the laser light emitted from the optical connector. A lens causes the laser light emitted from the optical connector to enter the wavelength converter. A luminaire emits the wavelength-converted light. The luminaire includes a holder that removably holds the optical connector. The optical connector includes: an optical component that is light-transmissive, mixes the laser light that enters, and emits the mixed laser light; and a case that has a light-blocking property and houses the optical component and part of the transmission component. The lens is in an optical path from the optical connector to the wavelength converter.

Abstract: A lighting device includes a laser light source that emits laser light, a wavelength converter that converts a wavelength of the laser light and emits wavelength-converted light, and a linear light guide that is elongated and guides the wavelength-converted light emitted by the wavelength converter and introduced through a longitudinal end surface. The linear light guide includes a lateral surface that emits the wavelength-converted light guided by the linear light guide. A proportion of the wavelength-converted light emitted by the lateral surface gradually increases with an increase in optical path length in the linear light guide.
